BEIJING, May 12 (Xinhua) -- Shanghai General Motors Wuling (SGMW) is to recall 19,680 cars over problems with the software of the engine's electronic control unit (ECU) from June 5, according to China's product quality watchdog.

The affected vehicles involve the Baojun 560 model manufactured from June 29, 2017 to Nov. 30, 2017, according to the State Administration for Market Regulation (SAIC).

The spring damper in the transmission will suffer from abnormal shocks because of the defect in the software of the engine's ECU, which will lead to a suspension of power output in extreme cases, SAIC noted.

SGMW said it would upgrade the ECU software and change the spring damper in the transmission free of charge for affected vehicles.
